So I've started using the TwitterFeed site to redirect my blog posts to Twitter. Now each of the posts on this site automatically get posted on my Twitter blog which saves a lot of time. The beauty of it is that it automatically truncates your posting to the 140 character limit that Twitter can handle as well as putting a TinyURL link to the original post in your tweet.
Setup is fairly simple one but it does require an OpenID to login. Luckily I was able to use my old Yahoo account. Next step is to tell TwitterFeed the address of your blog and the frequency to scan for new items.
